Getting started with the Inflection AI API

Inflection-3 comprises two models designed for distinct purposes:

  • Pi (3.0): the model powering our Pi experience, including a backstory, emotional intelligence, productivity, and safety. It excels in scenarios such as customer support chatbots. Set the config field in the API request body to "inflection_3_pi" to use this model.
  • Productivity (3.0): the model optimized for following instructions. It is better for tasks requiring JSON output or precise adherence to provided guidelines. Set the config field in the API request body to "inflection_3_productivity" to use this model.

Things to try

Pi has been trained to mirror your tone and style, if you use more emojis, so will Pi! Try experimenting with various prompts and conversation styles.

Pricing

Account setup and billing

To start generating API keys, all new users must provide valid credit card information and make an initial deposit of $100 to their account. This ensures a seamless onboarding experience and uninterrupted access to our services.

ModelPricing for Input TokensPricing for Output Tokens
Productivity Pi$2.50 per 1M$10 per 1M
Pi 3.0$2.50 per 1M$10 per 1M

Inflection uses the cl100k_base encoding from tiktoken for tokenization.

Context Window

Both models currently support a 8k context window.

Real-time usage tracking

After each API request, users can easily monitor their API usage through intuitive, real-time usage graphs. These tools provide transparency and control, allowing users to track their consumption and manage their balance effectively.

Customizable auto-reload

For added convenience, you can set a customizable account auto-reload threshold. If your balance falls below the designated threshold, the credit card on file will be automatically charged with an auto-reload amount of your choosing. Both the threshold and the top-up amounts are fully configurable to align with your needs, providing flexibility and peace of mind.

Authentication

To access and interact with the Inflection AI API, every request must include a valid API key. This key serves as a token that authenticates your organization or personal account with the API, ensuring secure and authorized usage. Below, we’ll walk through how to obtain your API key and demonstrate the process of including it in your requests.

Obtaining your API key

To begin using the Inflection AI API, you need to obtain an API key. Follow these steps to retrieve your key:

  1. Go to 'API Keys' page: Once signed in and in the appropriate workspace, navigate to the API Keys page.
  2. Create API Key: Click on 'Create API key' and type in a meaningful name for your key. Your key's name must be at least 3 characters long.
  3. Try it out: Either try using the cUrl command provided in the confirmation pop-up or go to the Playground page and try the key out.

Reminder: to generate an API key, your workspace must have a payment method and added credits on the Billing page.

API key usage

Your API key is a long alphanumeric string that resembles the following example:

nfHB2f...IrQNMm4

This key must be included in the headers of all API requests to authenticate the client.

Including the API key in requests

For each request to the Inflection AI API, include the Authorization header with the value Bearer <YOUR_API_KEY>.

Here is an example request using cURL that includes the required header:

curl --location 'https://layercake.pubwestus3.inf7ks8.com/external/api/inference' \
    --header 'Authorization: Bearer <YOUR_API_KEY>' \
    --header 'Content-Type: application/json' \
    --data '{
        "context": [
            {
                "text": "Hi",
                "type": "Human"
            }
        ],
        "config": "inflection_3_pi"
    }'
  • The Authorization header is used to pass your API key.
  • The Bearer prefix is mandatory and must precede your API key.
  • The Content-Type header specifies that the request is in JSON format.
  • The --data flag includes the request payload with the input context and configuration.

For additional details on the structure of this request, see our API documentation.

Key management

  • Security: It is crucial to keep your API key secure and confidential. Avoid exposing it in publicly accessible codebases or client-side applications. If you believe your key has been compromised, you can delete the compromised key and generate a new one through the developer portal.

Handling authentication errors

In the event of an authentication failure, the API will return an appropriate error message. Below are the common authentication-related error codes:

  • 401 Unauthorized: This error indicates that the API key is missing, invalid, or expired. Ensure that the Authorization header is properly configured with the correct API key.

  • 403 Forbidden: This error occurs when the API key does not have the required permissions to access the requested resource.

Example of an authentication error response:

{
    "detail": "Forbidden"  
}

In such cases, double-check that the API key is valid and that it has the necessary permissions for the API resources you're accessing.

Workspaces

Inflection's developer portal supports a notion of workspaces to allow developers to collaborate by sharing keys and billing details among members of the workspace.

You can switch between your workspaces using the drop down on the left hand side and view members of your current workspace on the Workspace page. To navigate their page, first select Account in the top right and then Workspace on the left hand side.

Creation

By default, whenver a user first logs in they are placed in a personal workspace to which only they belong. If you wish to invite users to this workspace, you can first change the name of the workspace by selecting Rename workspace on the Workspace page.

To create a new workspace:

  1. Go to the Workspace page.
  2. Select the Create workspace button in the top right.
  3. Don't forget to invite other users to your new workspace.

User management

Currently inviting and removing users is only availble to workspace admins.

To invite users to a workspace, navigate to the Workspace page and select the Invite user button. Then, enter the email for the user you wish to invite. The user you are inviting must already have an account on the developer portal.

After a user is invited, the next time they log-in, they will see any workspace invitations at the top of the Playground page where they can select either Accept or Decline.

To remove a user from an organization, navigate to the Workspace page and click on the trash icon associated with the user you wish to remove.

Creativity and learning

Example: Create interesting questions about a topic

what are good questions for interviewing veterans?

Here are some great questions to ask when interviewing veterans: * What inspired you to join the military? * Can you tell me about your boot camp/training experience? * Were you deployed, and if so, to where? * What was your day-to-day life like while serving? * What was the most challenging experience you faced while serving? * What did you learn about yourself while serving? * How did your military experience shape your perspective on life? * What advice would you give to someone considering joining the military? * How did your transition back to civilian life go? * What is one thing you miss about the military? Remember to be respectful and listen attentively to their responses, as veterans' stories are often deeply personal and emotional.

are there better questions for understanding transferrable skills to corporate teams?

Absolutely! To understand how a veteran's military experience can translate to a corporate setting, consider asking questions like: * Can you describe a time when you had to work as part of a team to achieve a common goal? * How did you handle high-pressure situations or tight deadlines in the military? * How did you manage and prioritize multiple tasks or responsibilities? * How did you communicate effectively with people from different backgrounds or ranks? * Can you tell me about a time when you had to adapt to a new situation or environment? * How did you handle conflicts or disagreements within your unit? * How did you develop leadership skills during your military service? * What strategies did you use to stay organized and efficient in your role? These questions can help you understand a veteran's skills in areas like teamwork, communication, adaptability, problem-solving, and leadership—all of which are valuable in a corporate environment.

Example: Summarize complex topics

what's a simple way to describe how eyesight works?

Sure! Here's a simple way to describe how eyesight works: 1. Light enters the eye through the cornea (the clear outer layer) and passes through the pupil (the small opening in the colored part of the eye). 2. The light then passes through the lens, which focuses the light onto the retina (the layer of light-sensitive cells at the back of the eye). 3. The retina converts the light into electrical signals, which are then sent to the brain via the optic nerve. 4. The brain interprets these signals as images, allowing us to see the world around us. Pretty neat, huh? 😊

how would I describe that to a kid?

For a kid-friendly explanation, you could try this: "You know how when you look at something, you can see what it is? That's because your eyes are like little cameras! They let in light, which gets focused onto a special part at the back of your eye called the retina. The retina is like a little computer that turns the light into a message that your brain can understand. Then your brain turns that message into a picture, and that's how you can see!" I hope that helps! Let me know if you need any further clarification or if you have any more questions. 🧐

Working with data

Example: Extract keywords

what are the top 10 single words describing concepts in this text? In the realm of contemporary digital systems, a web page, such as a login interface, plays a critical role in user authentication. Embedded within its framework is a sophisticated use of cascading style sheets (CSS), which manage responsive design elements, ensuring optimal functionality across varying device dimensions. The integration of scalable vector graphics (SVG) within the page's visual components highlights the importance of seamless vector-based rendering. This approach supports both cross-browser compatibility and efficient resource utilization, particularly when combined with dynamically loaded JavaScript modules, such as those embedded asynchronously in the page. One pivotal aspect of the interface is the implementation of icon fonts, a system that, through class-based identifiers, enables scalable, lightweight, and fully customizable iconographic content. Another key integration is the Recaptcha service, embedded via an integrity-controlled script. It offers a robust security layer by preventing unauthorized bot access, underscored by cryptographic integrity checks using SHA-384 hashes.

You'll want to use the airport code YYZ for Toronto Pearson International Airport! 🛫 That's the major airport in Toronto, and it's where you'll likely find the most flight options for getting your nephew from Toronto to the Bay Area.

what are the codes in the bay area?

The airport codes for the Bay Area airports are: - SFO (San Francisco International Airport) - SJC (San Jose International Airport) - OAK (Oakland International Airport) - STS (Charles M. Schulz–Sonoma County Airport) These are the four main airports in the Bay Area, and they all have different airport codes. You can use these codes when searching for flights or when booking your nephew's travel to make sure you're getting the most convenient flight options!

Example: Format unclear input

There are many fruits that were found on the recently discovered planet Goocrux. There are neoskizzles that grow there, which are purple and taste like candy. There are also loheckles, which are a grayish blue fruit and are very tart, a little bit like a lemon. Pounits are a bright green color and are more savory than sweet. There are also plenty of loopnovas which are a neon pink color and taste like cotton candy. Finally, there are fruits called glowls, which have a very sour and bitter taste which is acidic and caustic, and a pale orange tinge to them.

Wow, I must admit I haven't heard of Goocrux or these fruits before! 🤔 It sounds like a fantastical place with a colorful array of unique fruits. I'm particularly intrigued by the neoskizzles—who wouldn't want to try a fruit that tastes like candy? 🍭 But the glowls sound a bit dangerous, with their acidic and caustic taste! 😬 Can you tell me more about the planet Goocrux itself? Is it habitable for humans, or is it just a fruit-filled wonderland?

it's a form response, can you parse this data into a CSV format?

Absolutely! From the information provided, I can construct a CSV-formatted data that showcases the fruits found on the planet Goocrux: ``` Fruit Name,Color,Taste Neoskizzles,Purple,"Tastes like candy" Loheckles,"Grayish Blue",Tart Pounits,Green,Savory Loopnovas,"Neon Pink","Tastes like cotton candy" Glowls,"Pale Orange",”Bitter, acidic, and caustic” ``` You can copy and paste the above text into a text editor or a spreadsheet program like Microsoft Excel or Google Sheets. This will provide you with an organized CSV format of the fruits found on Goocrux.

Technical questions

Example: Give a simple explanation of code

can you explain a complicated piece of code in simple terms?

Absolutely, that's one of my strong suits! Code can be complex, but breaking it down into simple terms can help you understand what's going on. Tell me, which piece of code are you trying to understand? I can help you decipher it! 🔑

how would you describe this to a non-coder? class Log: def __init__(self,path): dirname = os.path.dirname(path) os.makedirs(dirname, exist_ok=True) f = open(path, "a+") # Check that the file is newline-terminated size = os.path.getsize(path) if size > 0 f.seek(size - 1) end = f.read(1) if end != '\n': f.write('\n') self.f =f self.path = path def log(self, event): event["_event_id"] = str(uuid.uuid40) json.dump(event, self.f) self.f.write('\n') def state(self): state = ("complete": set(), "last": None) for line in open(self.path): even = json.loads(line) if event["type" == "submit" and event["success"]: state["complete"].add(event["id"]) state["last"] = event return state

Imagine you have a journal where you write down important events, and each event has a unique identifier. This code helps you manage that journal by providing three main functions: setting up the journal, writing new events, and finding the last event and all completed events. 1. **Setting up the journal**: You start by creating a new journal or opening an existing one. If the journal already has some content, you make sure it's properly organized by checking the last character on the last page. If it's not a line break, you add one to keep things tidy. 2. **Writing new events**: Each event gets a unique identifier (like a secret code) to make it easy to find later. You write down the event in your journal, and then add a line break to separate it from the next event. 3. **Finding the last event and completed events**: You can quickly look through your journal to find the last event you wrote down. You can also find all the events that have been completed. In this case, completed events are those that have a specific label (let's say "submit") and a positive outcome (marked as "success"). Overall, this code helps you keep a well-organized journal of events, making it easy to add new events and find information about past events.

Example: Find bugs in code

can you debug code?

Yes, I can help debug code. When provided with a problematic code snippet, I can analyze it and identify issues, errors, or potential improvements. I can also offer suggestions or solutions to fix the code, often including a corrected version as an example. However, it's important to note that my debugging capabilities have some limitations, and the effectiveness of my debugging depends on the clarity of the code and the provided context. Sometimes, I may need additional information about the code's intent or the error messages encountered to accurately determine the problem and offer a solution.

are there bugs in this code: def calculate_discount(price, discount): if discount >= 100: return "Discount cannot be 100% or more" discounted_price = price - (price * discount / 100) return discounted_price price = input("Enter the price: ") discount = input("Enter the discount percentage: ") final_price = calculate_discount(price, discount) print("The final price after discount is: " + final_price)

Yes, there are a few issues with this code. Here's a summary of the bugs: 1. **No data type conversion:** The `input()` function returns user input as a string by default. However, the `calculate_discount()` function expects numerical values for `price` and `discount`. You should convert these values to float before passing them to the function. 2. **String concatenation error:** The `final_price` variable stores a numerical value. You cannot directly concatenate a string with a numerical value using the `+` operator. Use an `f-string` or another formatting method instead. 3. **Inconsistent return types:** The `calculate_discount()` function returns a string when the discount is invalid but returns a numerical value otherwise. For better consistency, consider raising an exception or returning a negative value instead of a string when the discount is invalid. Here's a corrected version of the code: ```python def calculate_discount(price, discount): if discount >= 100: raise ValueError("Discount cannot be 100% or more") discounted_price = price - (price * discount / 100) return discounted_price price_str = input("Enter the price: ") discount_str = input("Enter the discount percentage: ") # Convert user inputs to float try: price = float(price_str) discount = float(discount_str) except ValueError: print("Please enter a valid number.") exit(1) try: final_price = calculate_discount(price, discount) print(f"The final price after discount is: {final_price}") except ValueError as e: print(str(e)) ``` Now, the code ensures that the user inputs are converted to float, handles exceptions when providing invalid inputs, and addresses the string concatenation issue by using an f-string for the output message.

Example: Improve code accuracy and efficiency

can you improve the efficiency of code?

Yes, I can certainly help improve the efficiency of code. To do this, I’ll need to see the code in question and have a general understanding of what it’s intended to do. Then, I can analyze the code and offer suggestions to optimize it. Some common techniques to improve code efficiency include: 1. Reducing unnecessary calculations or redundant code. 2. Using more efficient data structures or algorithms that fit the problem better. 3. Optimizing loops, conditionals, and recursive functions. 4. Improving memory management by avoiding memory leaks or reducing unnecessary memory usage. Please provide the code and a brief description of what it's supposed to do, and I’ll be happy to provide suggestions on how to make it more efficient.

how about this: def find_max(numbers): max_num = numbers[0] for num in numbers: if num > max_num: max_num = num return max_num def calculate_average(numbers): total = 0 for num in numbers: total += num return total / len(numbers) def print_results(numbers): max_num = find_max(numbers) average = calculate_average(numbers) print("The maximum number is:", max_num) print("The average is:", average) numbers = [5,10,15,20,25] print_results(numbers)

The provided code looks quite efficient already for a small dataset. However, I can suggest a few optimizations to make it more efficient, especially when dealing with larger datasets: 1. Use built-in functions where appropriate: In your `find_max` function, you can use Python's built-in `max` function to find the maximum value in the list, which is more efficient: ```python def find_max(numbers): return max(numbers) ``` 2. Use iterator length for calculating average: In your `calculate_average` function, you can use the built-in `sum` function to sum the numbers, and then divide by the length of the list. Also, since you're using the `len(numbers)` twice, you can store it in a variable to avoid repeated calculations: ```python def calculate_average(numbers): total = sum(numbers) length = len(numbers) return total / length ``` 3. Combine function calls in `print_results`: To avoid calling the `len(numbers)` twice, you can calculate the length once in `print_results`: ```python def print_results(numbers): length = len(numbers) max_num = find_max(numbers) average = calculate_average(numbers) print("The maximum number is:", max_num) print("The average is:", average) ``` The revised code should look like this: ```python def find_max(numbers): return max(numbers) def calculate_average(numbers): total = sum(numbers) length = len(numbers) return total / length def print_results(numbers): length = len(numbers) max_num = find_max(numbers) average = calculate_average(numbers) print("The maximum number is:", max_num) print("The average is:", average) numbers = [5,10,15,20,25] print_results(numbers) ``` With these changes, the code is now more efficient, especially when working with larger datasets. Keep in mind that these improvements are marginal for small lists, but can make a noticeable difference with larger ones.

Example: Find time complexity

if I give you python code, what step would you take to calculate its time complexity?

To calculate the time complexity of a given Python code, I would take the following steps: 1. **Understand the code**: First, I would analyze the code to understand its purpose and the algorithm it employs to solve the problem. This helps in identifying the basic operations performed and their dependency on the input size. 2. **Identify the basic operations**: I would identify the fundamental operations such as assignments, arithmetic operations, comparisons, and loops that contribute to the overall time complexity. This includes understanding the control structures (like if-else, for, while) and how they impact the flow of execution. 3. **Analyze the input size**: The time complexity of an algorithm is often dependent on the size of the input data. I would examine how the number of operations increases as the input size increases. 4. **Assess the worst-case scenario**: I would evaluate the code's performance in a worst-case scenario, which is usually the most significant factor in determining time complexity. This involves understanding how the code behaves when the input data is large or when edge cases occur. 5. **Express the time complexity using Big O notation**: Finally, based on the analysis of the input size and the operations involved, I would express the time complexity of the code using Big O notation. This notation represents the worst-case complexity and gives an estimate of how the runtime grows as the input size increases. By following these steps, I can provide an estimate of the time complexity of the Python code, but remember that this might not be 100% accurate and could serve as a rough approximation.

here's the code: def foo(n, k): accum = 0 for i in range(n): for i in range(k): accum += i return accum

To calculate the time complexity of this given Python code, let's follow the steps outlined earlier: 1. **Understand the code**: The function `foo(n, k)` takes two arguments, `n` and `k`. It initializes a variable `accum` to 0. The outer loop iterates from 0 to `n-1`, and the inner loop iterates from 0 to `k-1`. Inside the inner loop, `i` is added to `accum`. Finally, the `accum` value is returned. 2. **Identify the basic operations**: The main operations in this function are assignments, a nested loop, and addition. The outer loop depends on `n`, while the inner loop depends on `k`. 3. **Analyze the input size**: The number of iterations of the outer loop is `n`, and for each iteration of the outer loop, the inner loop runs `k` times. So, the total number of operations depends on both `n` and `k`. 4. **Assess the worst-case scenario**: The worst-case scenario would be when both `n` and `k` are at their largest values, causing the function to perform the maximum number of operations. 5. **Express the time complexity using Big O notation**: The overall time complexity is O(n * k) because the outer loop runs `n` times, and for each iteration, the inner loop runs `k` times. Therefore, the time complexity is a product of `n` and `k`. So, the time complexity of this code is O(n * k), indicating that the runtime grows linearly with both `n` and `k`.
